Wyoming to California: master plumber license reciprocity

No credit· Start overVerified September 16, 2026· 8 sources

Wyoming does not issue a statewide master plumber license, so there is nothing to transfer. Here is California's standard path for out-of-state applicants.

Your origin state does not issue a statewide license at this level, so there is no license to transfer. The destination's standard out-of-state path is shown; expect to meet it in full.

Reference only, not legal advice. Rules change; confirm with the licensing board before you apply. Full disclaimer.

Original C-36 application (out-of-state experience counts; both exams required)

Your out-of-state credentials give no advantage. You meet the destination's requirements from scratch.

Except for Arizona plumbing classifications on CSLB's Reciprocal Classifications List, California does not waive the C-36 trade exam for an out-of-state master plumber or plumbing contractor license. Documented work as a journeyman or master plumber in another state counts toward the four years of journeyman-level experience in the past 10 years that the qualifying individual must show, then the applicant files the Application for Original Contractor's License, pays $450, and must pass both the Law and Business exam and the C-36 Plumbing trade exam through PSI within 18 months after CSLB accepts the application. CSLB still requires fingerprinting, a $25,000 contractor's bond (plus a $25,000 qualifying-individual bond where applicable), workers' compensation or an exemption, and the initial license fee of $200 (sole owner) or $350 (non-sole owner). NASCLA exam waiver is for B General Building only. City-issued origin journeyman or master plumber cards are not a CSLB classification and do not waive either exam.

Whether a particular out-of-state job title equals 'journeyman level' is decided on the application; CSLB publishes no list of accepted origin plumber licenses.

Surety bond

A license or contractor bond is bought from a surety, not the state. Price is a small percentage of the bond amount and depends on your credit.

  • Surety bond · $25,000

Liability insurance

Some states require proof of general liability or workers' compensation coverage at licensing time.

Business registration

If you plan to contract in your own name, budget for a business license or entity registration on top of the trade license.

How California licenses master plumbers

Issued by Contractors State License Board

California does not issue a license titled 'master plumber'. The statewide credential that sits above municipal journeyman cards is the C-36 Plumbing Contractor license from the Contractors State License Board. The license is issued to a business entity (sole owner, partnership, corporation or LLC) but is qualified by a named individual who personally meets the experience and exam requirements and is responsible for the classification, so an out-of-state master plumber or plumbing contractor who intends to contract in California applies as that qualifying individual. A master plumber who only wants to work as an employee needs no C-36 license (B&P §7053) and should instead check city journeyman-card rules. To qualify C-36, the individual documents at least four years of journeyman-level or higher plumbing experience within the past 10 years, pays the $450 original application fee, passes both the CSLB Law and Business exam and the C-36 trade exam through PSI within 18 months of application acceptance, is fingerprinted (DOJ $32 plus FBI $17 plus Live Scan rolling fees), posts a $25,000 contractor's bond (and a $25,000 bond of qualifying individual where applicable), carries workers' compensation or files an exemption, and pays the initial license fee of $200 (sole owner) or $350 (non-sole owner) for a two-year license. CSLB reciprocity can waive the C-36 trade exam for a contractor who has held an active license in good standing for the previous five years in an Arizona classification mapped to C-36 (C-37, C-37R Plumbing, K-37, K-77, L-37, L-77). Louisiana, Mississippi and North Carolina reciprocity entries are general building only; Nevada's published list as extracted has no class mapped to C-36. Even when reciprocity is granted CSLB retains the right to require the trade exam, and the Law and Business exam, bond, fingerprinting and all other licensure requirements still apply.

Why Wyoming has nothing to transfer

Wyoming master plumber

Licensed by cities and counties

Verified September 16, 2026· 13 sources

Wyoming issues no master plumber or plumbing contractor license; the State Fire Marshal's electrical program is the only statewide trade licensing and it has no plumbing component. The master credential exists only in city ordinances: Cheyenne's Master (8,000 apprentice hours plus 6,000 journeyman hours and an ICC/NICET/NASCLA exam), Casper's Master Plumber (apprenticeship or four years plus five years as a journeyman or master, ICC G27-N), Laramie's master plumbing certificate of qualification (three years beyond journeyman, city exam), Gillette's Master Plumber (five years plus the ICC exam), Sheridan's Master Plumber (2018 ICC G27 with Gas) and Jackson's Master Certificate of Qualification (ICC G-series National Standard exam plus time in service). In every one of these cities a plumbing contractor must be or employ a master of record, and the contractor license is a separate business license with fees from $150 to $300 plus insurance or bond. No city accepts an out-of-state master license: Casper, Gillette and Jackson reciprocate only with other Wyoming jurisdictions, Sheridan refuses all outside licenses, Cheyenne's Board has undefined discretion, and Laramie may waive its exam for an equivalent certificate from any governmental agency. Rock Springs registers contractors for $125 with proof of insurance and tests nobody.

How local licensing works in Wyoming

How local licensing works. There is no state plumbing board; each city's ordinance defines its own master-level license and the plumbing contractor license it qualifies. The reciprocity statute the cities cite reaches only other Wyoming jurisdictions, and no city publishes a route that honours another state's master plumber or plumbing contractor license.

Cheyenne. A Master level craft employee license (12.1.8) requires 4 years/8,000 hours documented as an apprentice (or certified equivalent training) plus 3 years/6,000 hours documented as a journeyman and passing results on a current ICC, NICET or NASCLA exam from the Board's list. Fees are $50 application plus $50 initial and $25 renewal. A Plumbing (C1) contractor - covering plumbing and pipe-fitting systems other than fire sprinklers - may be licensed only if it always employs a full-time master or qualified supervisor of that class, who may represent only one contractor (13.0); the C1 tested contractor license costs $50 application plus $200 initial and $75 renewal. Reciprocity is at the Board's discretion (3.3.2/3.5.1) with no published partner list and a statute limiting it to Wyoming jurisdictions.

Casper. Master Plumber ($75 new, $37.50 renewal) requires a federally recognized plumbing apprenticeship or four years in a Casper-licensed plumbing shop plus five years as a journeyman or master plumber in a Casper-licensed shop, and proof of passing ICC G27-N or equivalent. A Plumbing Contractor license ($300/$150) covers any plumbing work including steam and water boilers, must be backed by a full-time licensed master plumber, and requires $250,000/$500,000/$250,000 liability insurance. Reciprocal Master/Journeyman licenses ($50/$25) are limited to holders of a current license from another Wyoming jurisdiction with comparable testing.

Laramie. A master plumbing certificate of qualification requires three years as a journeyman (Table 15.24.020-1) and the building official's examination ($5 per attempt), or is issued without exam on presentation of a certificate from another governmental agency whose exam the board of examiners finds at least equal. All plumbing contractor work must be performed by or under the supervision of a master plumbing certificate holder, who must be available to the building official within 24 hours. The Plumbing Contractor license costs $300 new and $35 renewal and requires a business location and telephone, a $500,000 combined single limit insurance certificate naming the City and a Wyoming Workers' Compensation certificate of good standing; licenses and certificates run January 1 - December 31.

Gillette. Master Plumber ($50 new, $50 renewal) requires five years of approved experience and passing ICC examination results. A Class D Plumbing Contractor ($150/$50) works under the 2024 IPC, may not do gas pipefitting on its plumbing license, and must designate a Master of Record - a full-time employee or owner licensed as a Master Plumber, able to reach any job site within 48 hours and replaced within 60 days if they leave. Reciprocity (5-III-1(d)) is limited to active, good-standing licenses from other Wyoming local governments, with testing waived on proof of the ICC plumbing or contractor exam and no fee charged.

Sheridan. Master Plumber ($50 new, $50 annual) acts as Master of Record for a plumbing company, must show they meet the Plumbing Contractor requirements (2018 ICC G27 exam, four-year journeyman plumber verification on Form JP, two-year project verification on Form A) and pass the 2018 ICC G27 Master Plumber with Gas exam. The Plumbing Contractor license ($200 new, $200 annual) also needs a $1,000,000 liability insurance certificate and a $10,000 license and permit bond, and every plumbing business must hold both a contractor license and a Master of Record. The City does not accept licenses from other cities, towns, counties or states.

Jackson. The Master Certificate of Qualification card is the prerequisite for a Plumbing Contractor license and is the only individual card the Town still issues. It is obtained by passing the ICC National Standard trades exam through Pearson VUE (only G-series tests based on the 2018 I-Codes are accepted) and meeting the time-in-service requirement in JMC 15.36.050, or by reciprocity for someone 'currently licensed and in good standing in a Wyoming jurisdiction that meets our licensing requirements'. Applications go through the SmartGov portal with a 30-day processing window; the contractor license then requires the bond and insurance in JMC 15.36.035 and renews every December 31, while the Master COQ card renews triennially with six hours of ICC-accredited continuing education. Licensing covers only work inside Town limits.

Rock Springs. Contractors register with the Building Inspection Office ($125 fee and a certificate of insurance naming the City) before working; no master license or exam exists.
